Dickey <dickey@clark.net> 1996 # # $Id: shlib,v 1.7 2003/07/19 22:58:14 tom Exp $ # Use this script as a wrapper when running executables linked to shared # libraries on systems that use the $LD_LIBRARY_PATH variable and don't embed # the soname's path within the linked executable (such as IRIX), e.g, # # shlib knight # # Setting LD_LIBRARY_PATH, overrides/supplements the loader's normal search # path, and works on most systems. The drawback is that then the environment # variable has to be set to run the programs within this directory tree. # # For Linux (and other systems using the GNU loader), we can use the rpath # directive, which embeds the pathname of the library within the executable. # Using the Linux loader's rpath directive introduces a constraint, since # it's embedded into the binary, and means that the binary cannot be moved # around (though it'll work if the $exec_prefix convention that puts the bin # and lib directories under the same parent is followed). # # Using the actual soname (e.g., ../lib/libncurses.so) alone, is a more # flexible solution; you can link without having to set the environment # variable, and on some systems (IRIX) you can even run the resulting binaries # without setting LD_LIBRARY_PATH. # # Using a conventional link, with -L and -l options on Linux results in a # statically linked executable, which we don't want at all. # # Special cases: # # BeOS R4.5 uses $LIBRARY_PATH rather than $LD_LIBRARY_PATH. # # Make sure that we use the PATH that was set in run_tic.sh # if test X$NEWPATH != X ; then PATH=$NEWPATH export PATH fi q="" for p in lib ../lib do if test -d $p; then q="$p" fi done if test -n "$q" ; then if test -n "$LD_LIBRARY_PATH"; then LD_LIBRARY_PATH="$q:$LD_LIBRARY_PATH" elif test -n "$LIBRARY_PATH" ; then LIBRARY_PATH="$q:$LIBRARY_PATH" else LD_LIBRARY_PATH="$q" fi export LD_LIBRARY_PATH fi # cygwin doesn't use LD_LIBRARY_PATH, but does use PATH if test -n "$PATHEXT" ; then PATH=$LD_LIBRARY_PATH:$PATH; export PATH fi eval "$*"
